Slightly OT -- but in reference to some posts earlier: it is a good idea to carry with you at all times a complete list of all meds you take, RX as well as over-the-counter. I keep mine as a word document in the computer, modify it as needed, and print it out to give to my primary care doctor as well as any specialists I go to. Also, I get RX meds from two different sources, and it is a good idea to let each pharmacy have a complete list so they can monitor drug interactions.
And...I may have said this before but I'll say it again...the best type of doctor to prescribe antidepressants, etc. is a psychiatrist, and one who knows you and how you react to these types of meds.
I gave up smoking many years ago before there were drugs and other no-smoking aids. The craving stayed for a long time but is long since gone.
Good luck to anyone who is trying to quit!!
